> If something is failing with kerberos login, {{UserGroupInformation.loginUserFromKeytabAndReturnUGI()}} should fail with useful information. But not all exceptions from the inner code are caught and converted to LoginException. Those exceptions that aren't wrapped have their text and stack trace lost somewhere in the javax code, leaving on the text "login failed" and a stack trace of no value whatsoever.
